The tinge of fear that bubbled up inside Azriel's heart after getting those blows from Adeline was enough to emit the aura of fear that was strong enough to wake the demonic power of Adeline.
Adeline's eyes suddenly turned blood red and she went into a state of trance. She spread her arms and closed her eyes. Then she began to filter the aura of fear and she slowly began to absorb it all. She was attracting the aura as though she was a living breathing magnet.
After she absorbed the strongest aura that she had ever absorbed before, she took a deep breath in and then let out a satisfied moan. Adeline felt a new kind of sensation all over her body. She felt as though a dormant side of her had suddenly awakened. She did not consciously realize what had just happened but she suddenly felt as though she could even take down Azriel if she tried.
Adeline opened her sapphire eyes that were full of newfound confidence and power, and she glared at Azriel.
